Recent Results from T2K

Abstract:
T2K is a long-baseline accelerator neutrino oscillation experiment that studies neutrino oscillations by observing a disappearance of muon flavored (anti)neutrinos and an appearance of electron flavored (anti)neutrinos as they travel 295 kilometers across Japan. The analysis of T2K's data has produced world-leading measurements of leptonic CP violation, including a recent publication of the first substantial 3$\sigma$ constraints on the CP-violating phase, $\delta_{CP}$, in an April 2020 Nature article. The results from this analysis have since been updated to include 33\% more neutrino mode data and significant improvements to the neutrino interaction and flux models. This talk will present these latest results and discuss some details of the analysis employed in order to extract measurements of neutrino oscillation parameters from T2K's data.
